ADJUSTABLE SEAT.

Application filed January 2, 1926. Serial No. 78,921.

To all whom it may concern:

Be it known that I, KENNA D. TrroMrsoN, a citizen of the United Statesof America, and resident of Brooklyn, in the county ot Kings and Stateof New York, have 1nvented certain new and useful Improvements inAdjustable Seats, of which the following is a specification.

This invention relates to adjustable seats, and has referenceparticularly to a seat for use by operators of controls of hoistingmachinery, steam shovels, and for those of other occupations where it isdesirable for the operator to be seated.

It is an objectof this invention to produce a seat capable of adjustmentwith respeotto controls or machinery to be manipulated; and it is afurther object of this invention to provide novel means whereby the seatmay be moved vertically and in spaced relation to the controls ofmachinery to .be manipulated.

It is a still further object of this invention to provide novel meansfor adjustably supporting and holding a standard and to provide astandard with novel means whereby a seat may be adjustably held thereby.

It is furthermore an object of this invention to provide an adjustableseat of the character indicated having an anchorage to which thestandard may be expeditiously attached or detached so that the standardwith the seat maybe removed, if desired.

It is a still further object of this invention to produce a seat, anchorand support which can be constructed almost wholly by the cutting andstamping processes now in general use, resulting in minimizing the costof manufacture.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this application wherein likecharacters denote corresponding parts in the several views, and inwhich' v Figure 1 illustrates a view in side elevation of an adjustableseat embodying the invention Figure 2 illustrates a front elevationthereof;

Figure 3 illustrates a sectional view taken on the line 3-3 of Fig. 1;and

v Figure 4 illustrates a sectional view taken on the line l- I of Fig.1.

In these drawings, l'ha've shown an anchor or base comprising arelatively heavy metal plate having an approximately horizontallydisposed portion 5 with angularly disposed and downwardly extendingportions 6 and horizontally disposed portions 7 which rest on a floor orplatform usually occupied by operators. If, for instance, the seat is tobe associated with the operating levers for controls of a hoistingmachine or an excavating machine, the base will be stationed inconvenient location to the controls in order that the seat when adjustedwith respect to the .ase, as will presently appear, may be used incomfort by short or tall operators so that hand operated levers orpedals may be manipulated by the feet of the operator without fatigue.

The horizontally disposed portion of the base 5 has a longitudinallyextendingslot 8 and a clamping plate 9 is located under the saidhorizontally disposed portion. The clamping plate is held in differentpositions of adjustment with relation to the base.

through the medium of nuts 10, preferably wing nuts, which engagethreads on studs or bolts 11 carried by or projecting through theclamping plate. The threaded elements 11 project through the slot 8, ofthe horizontally disposed portion of the base and the clamping plate maytherefore freely move under the said base. The portions 7 of the basehaveapertures 12. for receiving bolts or lag screws or other fasteningsby which the base 'isanohored to the floor or platform, to whichreference has been made.

A standard 13, preferably of fiat metal of proper gage, has an angularlydisposed foot 14 which isslidable on the upper surface of thehorizontally disposed-portion of the base and .it has a transverse slot15 for the re ception of a threaded element 11, and when a wing nut hasbeen applied to the threaded element and screwed down to force the footinto engagement with the base, the parts will be held in differentpositions of adjustment and the standard may therefore be located indifferent positions with respect to the parts of machinery to beoperated As an auxiliary means for holding the standard and for bracingit, a brace plate 16 has a portion which stands parallel with thestandard near its lower end and it is secured to said standard bytastenings 17, such as bolts or the like. The brace has an angularlydisposed foot with a slot 16 to receive one of the threaded elements 11and the angularly disposed foot is engaged by a wing nut by which thebrace is clamped to the base. Preferably, the angularly disposed aortionoi": the brace and standard have their upper surfaces concave at theslots through which the threaded elements project and the wing nuts arepartially seated in these concavities when properly set to hold theparts in adjusted positions.

A bracket is secured to the standard near its upper end and the saidbracket is preferably formed from a plate of metal of suitable gagehaving a portion 18 which lies parallel with and is attached to thestandard and with portions 19 and 20 which extend outwardly at rightangles thereto. The angularly disposed portions 19 and 20 have threadedapertures 21 and 22, respectively, for receiving a threaded rod 23 onwhich the seat 24 is secured.

While any appropriate seat may be iounted on the threaded rod, there isillustrated, in the present embodiment of the invention, a conventionaltype oi seat that is used to a great extent on agricultural implements,although the inventor does not wish to be limited with respect to thetype of seat employed, since that may be changed to suit particularrequirements without departing from the spirit of ,the invention. Whenthe rod 23 is threaded in the apertures or the bracket, it may beadjusted vertically to make it convenient for people of ditierentheights, and by reason of the fact that the standard may be adjustedwith relation to the base, the. seat can be positioned in the mannerheretofore stated and for the purposes described.

As the functions of the several parts of the device have been stated inconnection with a description of the parts, a resume of the operation isbelieved unnecessary for an understanding of the invention by oneskilled in the art.

' The slot 15 extends inwardly from the edge of the foot 14 in adirection opposite that of the slots 15 in the foot of the brace 16, acondition which permits the standard and brace to be disengaged from thefastenings by a partial rotary motion of the standard.

I claim:

1. In an adjustable seat, a base adapted to be secured to a support,said base having a slot therein, a clamping plate under the base,threaded tastenings in the plate projecting through the slotof the base,a standard having an angularly disposed portion slidable on the base andhaving an aperture to receive one or" the tastenings, a brace secured tothe standard and having an angularly disposed portion slidable on thebase and provided with an aperture to receive another of the saidt'astenings, means engaging he fastenings for binding the clamping plateand the angularly disposed portions of the standard and brace in engagement with the base, a bracket secured to the standard near its top andhaving threaded apertures, a threaded rod adapted to be adjusted in theapertures of the bracket, and a seat on the said rod.
